I see the difference in the way the victim and perpetrator are treated. If someone robs your house and you see them running away, television strapped to your back, you call the police and give testemony. You say what you saw and the jury judges on the merits of the case. What doesn't happen, in a robbery, is the defense team lining up a slew of witnesses talking about all the times you left your house unlocked, all the times you invited other suspicious people over, all the times you sold something on Craigslist and all the times you Googled the price of the TV that got stolen. The defence doesn't use this testemony to show that you really wanted to give your TV away, and it wasn't actually stolen, and even if it was, weren't you sorta asking for it anyway?
